This value applies for tp ≤ 0.3 ms, duty cycle ≤ 10%. Derate linearly to 150°C case temperature at the rate of 0.32 W/°C. Derate linearly to 150°C free air temperature at the rate of 16 mW/°C. This rating is based on the capability of the transistor to operate safely in a circuit of: L = 20 mH, IB(on) = -0.4 A, RBE = 100 Ω, VBE(off) = 0, RS = 0.1 Ω, VCC = -20 V.
